Abstract
An improved ice penetrating arctic buoy for release from a submarine submerged under a layer of ice includes a Global Positioning System navigational processor receiver and/or a Emergency Position Information Radio Beacon and/or surveillance apparatus, an antenna for transmission and/or reception of appropriate RF frequencies, such as Global Positioning System or other R.F. frequencies found in the environment above the ice or EPIRB R.F. frequencies originating in the buoy into the environment above the ice. Convertor means converts navigational information and/or other information outputted from said Global Positioning System receiver into coded corresponding information and an on board transmitter sends such coded information acoustically or optically and/or electrically to the submarine via an underwater data link.
